I'm listening. What has changed? Why are they getting worse all of a sudden?
The answer is because there has always been a chorus of voices shouting lots of different things, most of the time we keep the problematic voices small, but recently we gave a bullhorn to a particularly shitty one. Society reflects that voices we amplify.
A few things. The recent uptick starts with 9/11. That put the US into a recession which drove down the demand for cheap immigrant labor. It also stirred up more anti race feelings of some groups (not all, some saw a boost). Then, the US started to go into the Middle East. In doing so, it destabilized the area creating a vacuum for extremest to fill which further destabilized the region. Then, the developed countries around the world started to go into a recession from the housing crisis. This again drove down the demand for immigrant labor, but, also drove down the aid to the Middle East which further caused issues in the region. At the same time, we had record low birth rates of groups that were historically in power.
Then, the world started coming out of the recession. The Middle East was still a cluster and getting worse. That pressure drove people out of places like Syria and pulled them to places in Europe where demand for cheep labor was going up. Because of the aforementioned low birth rates, the labor void was being filled by the immigrants in Europe which came from the Middle East area.
So now you have a huge influx of people being displaced that have been dealing with violence for a long time. You also have a big shift in culture as more people from a different culture move in. You then have competition for labor for low skilled people. You combine all of this and you see massive issues in Europe.
That is a far better answer than Trump gaining power. Your answer is horrible at explaining things outside of the US, and, even then it falls flat.
So, you were not listening...
